While I am pretty comfortable with the AR-15-type rifles/carbines, the same cannot be said WRT its bigger brother, the AR-10-type. I recently acquired an LMT 308 rifle that I want to convert from the standard VLTOR collapsible butt stock to the Magpul PRS stock.

With that thought in mind, I have three questions: What parts do I need? Are they different than the similar AR-15-type components? Will standard AR-10-type parts work, or do I have to go to LMT?

Thanks in advance for the information.

I dont have any experience with LMT 308, but I do have a DPMS 308 with a PRS stock.

The PRS stock requires a regular AR15 buffer tube...but the buffer and buffer spring are
308 specific...but the AR10 and DPMS are not the same if I'm not mistaken....

As far as the Stock, the Magpul runs a .308 specific version. As for the buffer and spring you CAN use an AR10 buffer and spring for any dpms .308 variant. In-fact, its recommended.
The reason you cannot use an AR15 PRS is the fact that the charging handle on the AR10's and variants are longer and will come into contact with the cheek rest of the smaller stock.
below are a few recommendations and links to Magpul's .308 stock...(the listed buffer/spring will work in both the PRS stock and collapsible stocks)

Also... below is a link of useful information from the .308 variant community here on Arfcom. Seeing as your rifle looks like it runs with an AR10 platform id imagine
you would be more inclined to check out the stats for the the AR10s not the .308 dpms platforms. More info for your new catch!

A MagPul MOE fixed stock works well on an LMT MWS... Get a rifle receiver extension (buffer tube), rifle buffer, and spring = good to go...
